Alongside published artists’ books that are still available on the market, there are also works that are not accessible, kept in museums, foundations or private collections, original projects owned by the artists themselves and preserved by them, and rare editions that are now out of print. ÓPLA gathers these particular books to make them more easily accessible to scholars, critics, teachers, graphic designers, illustrators, designers, publishers, researchers, university students and children themselves, in order to offer the possibility to view, compare, take ideas, discover trends and styles, find relationships.
